IMPROVEMENT IN APPARATUS FOR DISTILLING-PETROLEUM ND OTHER LIQU'IDS.

The Schedule referred to ln these Letters Patent and making of the same.

I, WILLIAM GRAY WARDEN', of Philadelphia, county of Philadelphia, Stateof. Pennsylvania, have invented an Apparatus for Vaporiing Liquids, ofwhich the following is a specification.

Nature and Object ofthe Invention. My invention consists of astll orboiler combined with certain ues and with -a fire-place in a. manner toofullyv described hereafter to need preliminary ex- 'A is a verticalcylindrical vessel of plate-iron, containing an internal Hue, B, whichis reduced in diam- `eter at x, and passesthence through the bottom ofthe vessel, as shown in fig. 1. I

The internal line B is closed at the top, immediately below which it isconnected to the outer vessel by -any desired number of horizontaltubes, a a.

A flange, b, is secured to the vessel, and this iiange bears on a plate,d, resting on the top of the brick structure D, inclosing the greaterportion ofthe vessel', between which and the brick-work intervenes anannular liuc, E. l

The fire-place F extends uninterruptedly entirely round the vessel, asshown in the sectional plan, iig. 2; in other words, the fire-place isannular, communicates directly with the liuc E, and has airy desirednumber' of openings, f, (ten in the present instance,) provided withsuitable doors, the grate at the opening being somewhat longer than thegrate between the doors.

` Beneath the brick structure is an arched chamber, G, into which thelower portion of the vessel projects, as shown in iig. 1, and with thisprojecting portion communicates a pipe, H, which, in case of asteamboiler', may represent a feed-pipe, and it' the vessel be used as astill, lit may represent the pipe through which the petroleum'or othermaterial to be distilled maybe introduced into the vessel.

The vessel may also be nrrnishedat or near its lower end with a blow-olior discharge-pipe, for disposing, from time to time, of such r-esiduumor sediment as may accumulate in the vessel. l

The products of combustion from the fireplace circulate freely throughthe annular' line E, round the vessel,pass through the horizontal tubesa a, `and thence downward through the central flue B and4 through thecontracted portion B of tli'e'samc to the ue I, which communicates withany adjacent chimney.

The object of contracting,r the internal flueot' the vessel at :c:4 isto permit a slight yieldingat that point during the expansion andcontr-action ofthe vessel, or of the flue itself. The outer vessel isalso at liberty to expand and contract at pleasure without disturbingthe brick structure upon which the vessellis suspended, so that when itexpands or contracts it 'will simply move to a limited extent in the-arched roof of the charnp It will be-seen that there is an extendedheatingsurface'exposed to the action of the fire, the greater portion ofthe vessel being enveloped by the products of combustion, the' heat' ofwhich becomes intensilied as the. products pass into and down throughthe iuternal due ofthe vessel.

Air maybe injected into the flue B, at about iig; 4, througha-perforated pipe, to elect more thorough combustion.

Claims. f 1. A still or boiler, consistingof a vessel, A, having aninternal flue, B, closedV at the top, so as to have a downward draught,in'combination with a continuous v annular flue surrounding the vesseland communicating with the fire-place, and, through tubes a, with thesaid internal flue, all substantially as set forth.

2. The combination of the vessel A, the continuous annular fire-placesurrounding the vessel, and the annular' iiue E, substantially asdescribed. In testimony whereofl I have signed my name to thisspecification in thepresencc of two subscribing l witnesses.

W. G. WARDEN.
